Title: Improvements in or relating to slow closing valves
IPC: F16K21/12
Filed: 1927-12-23
Abstract: 296,610. Yates, T. J. Dec. 23, 1927. Valves closing after a predetermined interval or flow. - A slow closing valve device, particularly applicable for controlling the supplies of hot and cold water to a washing machine, is adapted to be held in one of its open positions by a pivoted pawl engaging a rack pivoted to the actuating- levers, which pawls are adapted to be released simultaneously by hand or by automatic mechanism. Each valve comprises a piston 22 packed by a ring 20 and slidably mounted in a cylinder 15 screwed into the top of the casing and provided with a valve washer 21 held in position by a nut 23 having a serrated flange adapted to pass into the seat aperture 12 to give a gradual cut off. A narrow bye-pass groove 33 which may be of uniform or gradually increasing depth connects the inlet 11 with the chamber above the piston. The valve spindle 25 is furnished with grooves 30 where it passes through the piston and carries a pilot valve 26 adapted to engage a seat 27 held in position by a flanged member 28 screwed in a recess in the top of the piston. When opening the valve by means of a weighted lever 36, the pilot valve first releases the pressure in the chamber, thereafter the pilot valve engages the flange 31 on the member 28 to move the main valve to its open position. Each valve is held m its open position by a pawl 42 engaging a rack 40 guided by a shaft 43 and pivoted at 41 to the actuating lever 36. The pawls are simultaneously released by a cross member 48 on a member 46 pivoted on the shaft 43 engaging triggers on the pawls. The releasing gear may be actuated by hand or may be connected by a rod 49 to a balance lever 51, Fig. 6, carrying a vessel 53 coupled to the receiving vessel by a flexible pipe 54. As the receiving vessel fills the weight of liquid in the vessel 53 increases so that when a predetermined level is reached the catch mechanism is released to allow both valves to close slowly.

Abstract: 1482607 Magnetic tape recorder/player FUNAI ELECTRIC CO Ltd 12 Aug 1974 [30 May 1974] 35486/74 Heading G5R Channel-changing movement of a magnetic head 11, Fig. 1, in an endless magnetic tape cartridge recorder/player is effected by a cam (35), Fig. 12 (not shown), of a rotary body 21 which has a second cam 25, 26 engaged by control elements 32 at the end of a channel to thereby bring another cam 23, 24 of body 21 into driven engagement with a flexible roller 22 rotating with tape drive capstan 10 whereby the capstan 10 rotates body 21 to shift head 11. The apparatus may be used with 4-track, 2- channel or, as illustrated, 8-track 4-channel cartridges 1. Recording is selected by inserting cartridge 1 while a record slider 37 is manually held pushed in, a roller 7 engaging in cartridge notch 4 to retain the cartridge 1 and slider 37  being held in the operative position by engagement between a slot 44 therein and end 43 of a lever 40 which is pivoted by the cartridge 1 which also closes a switch 78 to energize capstan motor 14 via a normally closed section of a switch 47 on slide 37. Playback is selected by inserting cartridge 1 while slider 37 is in its inoperative position. When contacts 12 are bridged by an end of channel foil on the tape, electromagnet 29, Fig. 8, is energized to pivot an arm 28 causing a resilient plate 32 normally engaged in one of four notches 25 of the cam 26. to rotate the body 21 slightly to a position in which roller 22, normally located out of contact with body 21 in a notch 24 of the cam 23, contacts cam 23 and rotates body 21 until roller 22 engages in the next notch 24, the exact stop positions of body 21 being set by a resilient plate 33 engaging one of the notches 25. Body 21 carries switching contacts 83, 84 to energize channel indicator lamps and its cam (35) engages a screw (36) on a plate 17 carrying head 11. At the end of recording the fourth channel the above actions are repeated and in addition a pin 55 on body 21 pivots a lever 54 causing a member 53 to operate switch 47 to a position maintained by engagement of a hook 61 on resilient plate 59 with member 53, whereby the normally closed section of switch 47 opens to stop motor 14 and a normally open-section of switch 47 closes to energize a solenoid 50 to retract an arm 65 whereby a spring 71 pivots members 62, 68 releasing roller 7 from cartridge notch 4 and allowing spring 75 to eject the cartridge 1 by means of a member 76, lever 40 thereby pivoting to release slider 37 for return by a spring 46 to its inoperative position. Ejection is not effected during playback, channel 1 being repeated after channel 4. A modification, Fig. 13 (not shown), has four pins 55 on rotary body whereby the cartridge is ejected at the end of each channel during recording. In another modification, Figs. 14, 15 (not shown), flexible roller 22 engages a face cam of body 21 rather than a generally cylindrical cam surface and the roller 22 is driven from the capstan 10 via a right-angle-drive rather than being coaxial with capstan 10.

Sheets L in a hopper 30 are fed one by one by a roller 32 co-operating with members 34 to rollers 36, 38, the latter being driven, and thence over a feeler 260, which is thereby depressed to close a switch 250, and against a feeler 28, which is thereby pushed to the position of Fig. 21, where it acts as a front stop for each sheet. Movement of the feeler 28 actuates a clutch to initiate one revolution of a postage metering drum 24 co-operating with an impression cylinder 26, and at the same time closes a switch 252. When switches 250, 252 are both closed, a solenoid is energized and de-clutches the drive for the rollers 32, 38. A cam mechanism releases the feeler 28 as the printing plate begins to contact the sheet, and the sheet is then moved forwards by the drum 24 and cylinder 26 over the feeler 28, rollers 32, 38 being allowed to rotate by an overdrive. When the trailing end releases the feeler 260, the drive to rollers 32, 38 is re-started, and the next sheet is fed until it reaches the feeler 260, when the drive is again stopped. When the trailing end of the first sheet releases the feeler 28, the latter moves back to the position of Fig. 20, re-starting the feed rollers, and the second sheet is fed to the position of Fig. 21, this feed cycle and printing cycle being repeated indefinitely.
